Where is the commercial solar opportunity in Greer?
Greer’s business base runs from Trade Street shops to some of the biggest industrial sites in the state.
BMW Manufacturing’s Plant Spartanburg, at 1400 Highway 101 South in Greer, employs more than 11,000 people on a 10-million-square-foot campus and assembles more than 1,500 vehicles a day, according to BMW.
SC Ports’ Inland Port Greer, a 91-acre rail terminal served by Norfolk Southern, moves containers overnight between the Port of Charleston and the Upstate, and draws warehouses and logistics firms to the area.
Sites of that size sit far outside CPW’s published solar limits.
The realistic commercial solar market inside Greer CPW’s published rules is smaller businesses: offices, shops, restaurants, churches, light-industrial units and the service firms around the larger plants, provided their demand is under 30 kW for code 704 and the system is 100 kW or less for Tier 2.

Which Greer businesses fit solar best?
Retail, restaurants and offices
Daytime trading hours match solar output. On code 704, a business using under 3,000 kWh a month offsets energy at 13.85¢, the highest block, so self-use is worth more than twice an export.
Warehouses and logistics near the inland port
Large flat roofs, but often low daytime load per square foot. A roof sized to the roof, not the load, would export most of its output at the lower credit. Many larger sheds also exceed code 704’s 30 kW demand limit.
Manufacturing suppliers
Process loads can absorb all solar output, which is the best economic case. Most exceed 30 kW of demand, so CPW must tell you what rate and interconnection terms apply.
Schools, churches and nonprofits
Weekend and summer exports from a school or church earn mostly off-peak credits; model those hours honestly.
Hotels and farms
Hotels run steady loads day and night; daytime self-use is what pays. Farm operations are covered on solar for farms near Greer.
How do demand and demand charges affect commercial solar in Greer?
Code 704 has no separate demand charge in its base charges: it bills a facilities charge and energy. That makes small-business solar on CPW simpler to model than on many utilities, because there is no risk that a cloudy afternoon leaves a demand peak the panels were supposed to shave.
It also caps eligibility. Once a business’s demand reaches 30 kW it falls outside code 704, and we found no published CPW renewable rate for larger commercial customers. Before commissioning a design, ask CPW at 864-848-5500 which rate and interconnection terms apply to your account, and get the answer in writing.
How should a Greer business size solar and judge the return?
Start from twelve months of interval or monthly data. Because code 704’s first block is the most expensive, the first 3,000 kWh of monthly self-use saves 13.85¢ each; savings per kWh fall to 10.96¢ and 9.95¢ for larger users, and exports earn 6.54¢ or 4.251¢.
A system that covers a smaller business’s daytime load usually beats one built to fill the roof.
Return depends on price, self-use share, tax position and the credits. We do not publish commercial prices.
A proposal should show simple payback, the effect of the tax credits on cash flow, and the assumption about future CPW rates.
CPW limits AC size (DC × 0.85) to 90% of the service rating unless you pay for an upgrade.

Which incentives and financing fit Greer commercial solar?
The South Carolina Clean Energy Credit (Form TC-54) is the main state incentive for businesses, capped at $500,000 a year with a 15-year carryforward.
Leased and business systems may use §48E; it ends for wind and solar placed in service after 2027 where construction begins after 4 July 2026 (Form 3468 instructions; Notice 2025-42).
The separate Solar Energy Property Credit (TC-58) for very large systems is listed by SCDOR as repealed at the end of 2024.

Businesses can buy with cash or a loan, or lease from an ORS-certified lessor. CPW’s agreement bars any arrangement in which you buy electricity from a third party, so a commercial PPA is not available on CPW.
Storage follows the same logic as for homes: code 704 has no demand charge or time-of-use energy price to shave, so a battery is mainly for resilience. Solar financing in Greer.
How to evaluate a commercial solar proposal in Greer
Code 704 if demand is under 30 kW; otherwise a written answer from CPW on the rate that applies.
$250 fee, IEEE 1547 / UL 1741 documents, and a $300,000 general liability certificate kept for the life of the connection.
City of Greer commercial plan review is half the permit fee, paid at submittal.
Each priced separately: your 704 energy block for self-use, 6.54¢ / 4.251¢ for exports.
CPW and PMPA hold a first right of refusal before you sell renewable energy certificates to anyone else.
Not permitted on CPW. Treat it as a red flag.

Primary-source research, data analysis and fact checking
We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.
Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.
- 160
- primary sources read and cited
- 228
- figures with a retrieval date
- 115
- federal and state government sources
- 66
- researched pages published
How this desk works
- Primary sources only. Statutes from the legislature’s own publishing system, federal data from the agency that collects it, code text from the adopted edition, manufacturer claims from the data sheet. We do not cite an article that cites a source; we go and read the source.
- Every figure carries its provenance. A named document and the date we retrieved it, so you can check it and so you know how old it is. Retrieval dates are not decoration: an EIA rate from May is a different fact from an EIA rate from August.
- We publish what we could not verify. Every research page carries a section naming the things we tried to establish and could not, and why. A paywalled standard, a state website that refused the request, a manufacturer that publishes no figure at all.
- We separate measurement from modeling from our own reasoning, and label which is which on the page. A laboratory measurement, an assumption inside a modeling tool and our own inference are three different kinds of claim and they are never presented as one.
- We do not sell solar, and we take no payment for placement, ranking or a favorable mention. Nobody buys a position on this site.
Data as of Last verified 5 October 2026. Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
